Gaia Data Release 4: Modelling of drift-scan related effects in Gaia's point spread function
Nicholas Rowell, Michael Davidson, Nigel C. Hambly +5
An accurate model of the point spread function is required in order to estimate positions and brightnesses of stars in digitized images. The PSF of the Gaia space telescope is unus…
Gravitational waves and small-field astrometry
Robin Geyer, Sven Zschocke, Michael Soffel +3
Astrometric observations can, in principle, be used to detect gravitational waves. In this paper we give a practical overview of the gravitational wave effects which can be expecte…
Influence of a continuous plane gravitational wave on Gaia-like astrometry
R. Geyer, S. A. Klioner, L. Lindegren +1
A gravitational wave (GW) passing through an astrometric observer causes periodic shifts of the apparent star positions measured by the observer. For a GW of sufficient amplitude a…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Gaia Focused Product Release: Asteroid orbital solution. Properties and assessment
Gaia Collaboration, P. David, F. Mignard +2
Context. We report the exploitation of a sample of epoch astrometry for 157 000 asteroids, the same object in the Gaia Data Release 3, extended over the time coverage planned for t…
